Spherical Niobium Powder

Spherical Niobium Powder

Spherical Niobium Powder refers to a type of niobium powder that has been processed into spherical particles through atomization or other techniques. This type of powder has a uniform particle size and shape, which makes it ideal for various applications such as 3D printing, powder metallurgy, and surface coating.

Spherical niobium powder is produced by melting niobium in a furnace and then atomizing it into small droplets using a high-pressure gas. These droplets solidify into spherical particles as they cool down, resulting in a powder with a narrow particle size distribution and high flowability.

Spherical niobium powder is used in a variety of applications, including additive manufacturing of aerospace and medical components, production of superconducting wires and magnets, and as a coating material in the semiconductor and optics industries.

Spherical Niobium Powder Application

Niobium is the lightest refractory metal. It has the characteristics of high melting point, high-temperature strength and specific strength, and no radioactivity. It is the preferred thermal protection material and structural material for aerospace engines. Radiofrequency plasma spheroidized niobium powder has the characteristics of high sphericity, good fluidity, high purity, large loose packing density, the full internal density of the particles, and no hollow powder. It is widely used in palladium materials, vacuum coating, thermal spraying, coating, cold spraying, and other fields.
